Constant DSL Disconnection and now packet loss

Over the past week I've had to ring up around ~7 times, once per day, due to constant disconnections.

After speaking to one of your agents this afternoon I can see that not only has the broadband speed lowered and become even more unstable than before, but we're actually suffering from packet loss.

I pinged PlusNet, Google and OpenDNS servers to find similar results every time, worst case scenario was 85% packet loss, which is completely unacceptable, after pinging PlusNet's secondary DNS server, a screenshot of which has been attached.

In my opinion we are definitely not receiving the service that we're paying for, and PlusNet certainly isn't living up to expectations for me.
